Abstract
Method and software product for transferring data, plus equipment for controlling data transfer in a multimedia system that includes a group of participants' terminals, with which multimedia data generated by participants' terminals contained in the group are sent to one or more participants' terminals contained in the group and played back there. A central synchronization unit generates synchronization labels containing time information and sends them to the participants' terminals contained in the group, and the synchronization labels are used to play back information in modified time.

A method for transmitting data in a multimedia system that includes a group including participants' terminals, with which multimedia data generated by participants' terminals contained in the group are sent to one or more participants' terminals contained in the group and played back there, comprising:
- generating synchronization labels through a central synchronization unit, said synchronization labels containing time information, and sending them to the participants' terminals contained in the group;
- receiving the synchronization labels through each of the participants' terminals contained in the group, attaching the received synchronization labels to the multimedia data generated in the participants' terminal, and sending the multimedia data with the received synchronization labels attached to the central synchronization unit;
- receiving, through the central synchronization unit the multimedia data with the attached synchronization labels, modifying the time information contained in the synchronization labels according to a time context for the multimedia data sent by the participants' terminals, and sending the multimedia data to the participants' terminals to be played back;
- and
- receiving the multimedia data with the attached modified synchronization labels through the participants' terminals and playing back the multimedia data in the time context corresponding to the modified time information contained in the synchronization labels.
A system for controlling data transfer in a multimedia system, comprising:
- a group of participants' terminals with which multimedia data generated by participants' terminals contained in the group are sent to one or more participants' terminals contained in the group and played back there, comprising:
- central synchronization unit generating synchronization labels containing time information and sending them to each of the participants' terminals contained in the group, wherein the participants' terminals receive the synchronization labels and attach the received synchronization labels to the multimedia data generated in the participant's terminal and send the multimedia data with the received synchronization labels attached to the central synchronization unit, and
- wherein the central synchronization unit receives the multimedia data with the attached synchronization labels from the participants' terminals and modifies the time information contained in the synchronization labels according to a time context for the multimedia data by the participants' terminals and sends the multimedia data to the participants' terminals,
- wherein the multimedia data with the attached modified synchronization labels is received in the participants' terminals and played back in the time context corresponding to the modified time information contained in the synchronization labels.
